Woody and his sister

(
)

And you thought he was an only child who grew up under a roller coaster. Alas, “Annie Hall”-ics, it’s not true. Tumultuous as his life has been, the former Allen Konigsberg, a k a Woody Allen, grew up in the Flatbush and Midwood sections of Brooklyn without the quake and roar of an overhead Cyclone. But he did have an adoring younger sister who — after Allen’s bitter feud with longtime producer Jean Doumanian — took over as the businesswoman behind the filmmaker.

Today, Letty Aronson — the former Ellen Letty Konigsberg, now a widowed teacher with three grown children and a nimbus of reddish hair — traipses across Europe raising money for Allen’s films. She also nudged him into his latest Broadway outing: writing one of the trio of one-act plays (the others are by Ethan Coen and Elaine May) that make up “Relatively Speaking,” opening Thursday.

“Letty is a first-rate producer,” Allen, 75, tells The Post. “And being she is my sister, she’s always watching my back.” And front and rib cage. (Hey, we said she was adoring.) Let’s let Letty take it from there.

BROOKLYN DAYS

“We’re eight years apart. From the day I was born, Woody called me Letty, which is my middle name, because he preferred it. My parents called him Allen till the day they died. I guess they were [like the quarrelling parents of “Annie Hall”]. My mother worked as a bookkeeper and my dad was everything: a jewelry engraver, a waiter, a taxi driver. They always thought Woody should be a pharmacist, because that was a good, solid, respectable way to earn a living.

“He was a terrible student. He was thrown out of NYU film school — he didn’t go, he didn’t do the work and very quickly he was out of there. He barely got through high school. I think he went to the New School and dropped out or got thrown out of that. But Woody always did what he thought was best for him.”

MOUNT SINAI ON SPEED DIAL

“I wouldn’t call it hypochondria. He’s cautious. Someone else may have a wait-and-see attitude, but Woody will check it out before you would. But it’s not hypochondria. . .

“He has amazing energy, amazing! We get to Rome, all of us are exhausted, but the next morning, even with the jet lag, he’s up looking for locations. Look at this play: He goes to at least seven if not all eight performances a week, to give notes to the cast. He’s very health conscious. He exercises every day — he does treadmill and weights — and he eats very carefully.

“He has an iPhone. However, he doesn’t do e-mail and uses it as a phone and to check the weather.”

FILMING THE WOODY WAY

“It’s much easier for me to raise money in Europe. Woody has final cut, he has 100 percent control of everything. And the [American] studios don’t want that.

“He makes a film every year. He would tell you that he has more ideas than he has time to do them. I don’t think he has a favorite because once he finishes them, he never looks at them again — because he’s going to find something he could have done better.

“When I read the script for ‘Midnight in Paris,’ I thought, Who is going to see this movie? Practically no one anymore has heard of Gertrude Stein. I told him, ‘This is not going to be on anyone’s radar screen.’ But he always makes the films he thinks he should make, and I support that. But I thought, Oh my God, people who invest in this film. . .”

EX-WIVES & LOVERS

“When he married his first wife [Harlene Rosen, in 1954], he was 20 and she was 17 or 18. She was very nice and very smart, but of course they were two kids. Then he was married to Louise [Lasser]. She’s great — we see her on Thanksgiving. Diane [Keaton] and Woody stay in touch all the time. They’re still very good friends. He’s good at retaining all those friendships.”

BUT NOT WITH MIA FARROW

“We have absolutely no contact because of what she did” — accusing him of molesting their daughter Dylan after he took up with her 21-year-old daughter, Soon-Yi Previn, now 41 — “was unconscionable. Encouraging the children not to like him and not to want to see him! She’s changed [their son Satchel’s] name six times. I don’t know what it is now. I think it’s terrible!”

LIFE WITH SOON-YI

“They have a great marriage. They get along well, they’re interested in the same things. They have the two children, a wonderful house, they entertain, they travel — they lead a very nice ordinary life. He’s an excellent father and takes his kids to school in the morning.”

GOOD-ENOUGH SON

“I’m not sure my parents were able to grasp his importance in the world of film, or the nature of his celebrity. To them he was Allen who stopped over at their house. My father was very taken with the whole show-business thing. My mother wasn’t easy to please. Would she have been as proud if Woody were a successful pharmacist? Probably.”
